ICE-DUMP.

SPECIFICATION forming part'of Letters Patent No. 593,680, dated November 16, 189'?A Application led March 19, 1897.

vcalled to the accompanying drawings, with the reference-numerals marked thereon, which form a part of this specification.

This invention relates to improvements in ice-dumps, which are devices used in connection with the manufacture of artificial ice. As is Well known the water for such purpose is frozen in vessels or tanks', the ice blocks produced assuming then the interior shape of these freezer vessels, lling them out with such a close and tight iit that removal of the ice blocks is not readily accomplished and, in fact, is not possible until the dimensions of the latter have been somewhat reduced by melting. Since these freezers when filled are of considerable weight, ice-dumps have been provided to facilitate their handling, particularly for the purpose of turning them in av manner to permit the ice block to slide out. To accelerate such sliding out, steam or hot water is applied against the outside of the freezer vessels to start the melting of the block in order to loosen it from the walls of the vessel.

My improvement-s relate particularly to an addition of the means for applying the medium which induces the melting with an object of obtaining quicker results.

They also relate to certain mechanical additions and details of construction, all of which are fully explained in the following specilication and claims, which form a full description of the invention, its operation, parts, and construction, which latter are also illustrated in the accompanying drawings, in which- Figure 1 shows a side elevation of an icedump in the act of dumping and provided with the improvements contemplated by my invention. Fig. 2 is a front elevation with parts insection of the same as shown in Fig.

1, but with the freezer Vessel removed. Fig. 3 is a sectional view of the lower pipe connection and taken on a line 3 3 of Fig. 1.

6 is the body vof the dump which receives the freezer vessel 7, in which the water is frozen and is therefore of a size to freely admit such vessel. These latter are mostly oblong, and the body 6is therefore shaped accordingly, being a box-shaped contrivance with one of its ends and narrower sides removed. From each of the broadv sides project trunnion-journals 8, which rest in bearings 9, formed in the upper part of standards 10, and whereby the dump is pivotally supported so that it may be readily manipulated. For receiving a freezer vessel the body is swung to a position, as shown in dotted lines in Fig. 1, which permits introduction of the former through the open narrow side at 11. The dump is then swung around in a manner tobring its open end 12 with the open end of the freezer vessel in such a position as to permit the ice block to readily slide out of the open end ofthe freezer vessel, as may be seen in full lines in Fig. 1, where the ice block is shown as having started to leave vessel '7. The dump is sustained in this position by a sill 13, and which is so located and of such height as to guide the ice block upon a short chute or inclined plane 14. This sill is preferably of wood and is supportedr on an iron bar 15, which permits ready and independent removal of the sill whenever necessary.

After the ice block has beenl discharged and theempty freezer vessel removed the dumpis ready Vto receive another charged vessel, having first been put again in a position,l as shownin dotted lines in Fig. 1. It is preferable to provide means which hold the loosely-supported dump firmly in position while being loaded, and for which purpose a spring-catch 16 is provided, which is so located in a fixed position below the dump asto be within the pat-h of a locking-pin 17, secured yto the lower end of the dump, and which pin IOO dumping, the spring catch is simply depressed, for which purpose a laterally and upwardly projecting tread 21 is provided.

To hasten the loosening of the ice block from within vessel 7 after dumped, steam or hot water is applied from pipes 22, 23, and 24, the ends of which are closed, the discharge being in form of a spray through numerous openings in the side of the pipes. These latter and the discharge-openings in them are so located that from pipe 22 the spray plays over the top and sides of vessel 7 (considering position of parts as shown in Fig. 1.) From pipe 23 its back is reached, and pipe 24 discharges against the bottom. The necessary space for pipes 23 and 2i is obtained by proj ections upon which vessel 7 rests and which prevent it from resting on these pipes, providing thereby also the necessary space to permit the spray to spread sufficiently to reach fully the particular surfaces. These projections are constructed in form of timbers 25 and 2G, the first being in the short end and supporting the vessel when first put in with the position of the dump, as shown in dotted lines in Fig. 1. After dumping-that is, when in position, as shown in Fig. 1 in full lines-the vessel rests on timbers 26. Catches 27 at the outer ends of the latter prevent the vessel from sliding out with the ice. The spray-pipes are supplied from a pipe 23, which divides into branches 29 and 31, the first supplying pipe 22, the other passing through the narrower side or bottom for the time being when in dumping position of body G and supplying pipes 23 and 2i. An interposed cutolf device controls this supply automatically in this manner, that when body G is in position for receiving the supply is cut olf, but is turned on as soon as it arrives in position for dumping. This cut-off device consists of a cock, the plug of which is formed by one of the trunnion-journals S, which is hollow for such purpose, as shown at 32, and with which hollow part pipes 29 and 31 communicate. The

' housing for the cock is formed by the bearing 9 for the particular journal. Pipe 2S connects to this bearing, passing through it, and cockjournal S 32 has a port 33, which is so located that when the parts are in position for dumping this port registers and establishes communication with the open end of the pipe 28, as shown in Fig. 2, the hot water passing through bore 32 and into pipes 29 and 31, and before and after this time-that is, while the dump isin position for receiving vessel 7-such communication between bore 32 and pipe 2S is shut off, as shown in Fig. 4. Stuffing-boxes are provided for the cock at the ends of its bearing to receive suitable packing to prevent leakage, the packing being held in place by glands 34 and 35. The discharge from the pipes may be regulated by valves 3G and 37, and entirely cut oif from either the upper or lower branches. The entire discharge is regulated and controlled by valve 38 in pipe 2S.

39 is a catch-basin, catching the waste water and drip from the melting ice and the spray. Its upper flange may be used to support the base of standards 10, and the iron bar 15 supporting sill 13.

As will be seen no extra cock nor any dcvices for operating it are required, its parts being formed by one of the trunnions and by the bearing of the same. NVhilc spray-pipes acting against the top and upper side of the freezer vessel have been used before,- the application of such pipes against the under side of the vessel is broadly new with me. These latter pipes are, however,very important, and one pipe applied against the bottom of the freezer vessel gives quicker results than any number of pipes applied elsewhere, because the melting is from the bottom and the loosening of the ice block is accelerated by its weight, which causes it to sink into the space created by the inciting.

I'Iaving described my invention, I claim as new- 1. In an ice-dump, the combination of a body 6 open in a manner to be capable of discharging and receiving a freezer vessel and pivotally supported to permit it of being swung into the necessary position for either purpose, and a heat-conveying pipe 24 being below the freezer vessel and discharging against the under side of it when the parts are in position for dumping.

2. In an ice-dump, the combination of a body open in a manner to be capable of discharging and receiving a freezer vessel and pivotally supported to permit it of being swung into the necessary position for either purpose, timbers 25 upon which the vessel is deposited when put into the dump and timbers 26 which support it while in dumping position and heat-conveying pipes 23 and 2i between the timbers, discharging respectively against its back and under side of the freezer vessel while in position for dumping.

In testimony whereof I hereunto affix my signature in presence of two witnesses.
